Scientists concerned about endangered orca still pushing body of her calf

An endangered orca is not letting go of her newborn calf, whose body she has been pushing through the water for more than two weeks.

The whale known as J35 was spotted in coastal waters near the border between British Columbia and Washington state Wednesday with the carcass of her calf that was born and died on July 24.

Sheila Thornton, a research scientist with Fisheries and Oceans Canada, said experts are becoming concerned that the whale’s behaviour will interfere with her ability to forage.

No intervention is planned, she said, but they will monitor her condition.

“I certainly think the duration of carrying the calf is unprecedented,” she said during a conference call with reporters on Thursday.

“You can look at that as mourning behaviour, there are a lot of different theories out there. It’s very difficult to say, but certainly they’re very intelligent animals and the loss of this animal is quite profound for both the (killer whales) and I think for everyone who witnesses this.”

The earliest the weather is forecasted to clear up is Sunday, Hanson said, and the plan will be easier if the whales move closer to the coast.

The experimental, emergency plan to save J50 requires scientists to nail down her ailments through breath and fecal samples, then administer long-lasting antibiotics by either pole-mounted syringe or dart. If that goes well, they say they will try feeding her Chinook salmon filled with other medication.

The plan hit a snag in Canada, which has taken longer to get licences in place than in the United States. But as of Wednesday night, Fisheries and Oceans Canada says it has received an application from NOAA to administer the antibiotics. The salmon-feeding plan is still under review.

“We are working closely with NOAA and are considering every possible option available to us to save this whale. Our decision will be evidence-based and we will act quickly together with our partners when the conditions are right to move ahead with any action,” the federal department said in a statement.

“We are prepared to issue permits for the best course of action for this whale without delay.”
